Pyle Pro PDC21 Reviews

Great value for a useful box

By Chris

Playing from a silent platform, I needed to be able to use 1/4" out to XLR - and this box is super useful and easy to use. I've mounted it to the bottom of my pedal board so it's not taking up any real estate and out-of-sight. Greta vlaue!

It works!
